After running CanopyDriver.run on some 4 dimensional DenseVectors, I'm
using a handcrafted text dictionary passed to ClusterDumper declared
as dictionary type text. The dictionary looks like this, with the
entry lines having dimension and feature name separated by tab:
0 recordedBy
1 recordNumber
2 eventDate
3 locality
ClusterDumper is throwing lots of lines like
14/03/30 16:51:08 ERROR clustering.AbstractClusterWriter: Dictionary
entry missing for 3
apparently for each cluster (and of course, for varying dimensions).
Is there a prohibition on using a text dictionary when the underlying
data are DenseVectors? If not, what is causing this error?
Running mahout 0.9 under eclipse on Ubuntu 13.04
Thanks
